@unnikrishnan the electron when absorbs energy goes to higher shells , having higher n-values , not higher energy as this movement gets it to closer to continuum. the deepest energy levels are the K- level - you are in a potential well and more deeper you go you will reach more ... - Why are lower energy systems stable? - Physics Stack ExchangeHowever, a system in a high energy state doesn't need external energy to tranform to a low energy state. There may be a higher barrier between the high and low energy states so that a initial push is required. However, once that push occurs, the system emits overall energy.
- thermodynamics - Why does the nature always prefer low energy and ...The decrease of potential energy is the consequence of the first (energy conservation) and second (evolution to more likely macro states) law of thermodynamics. As macro states with a lot of energy stored in heat (random thermal motion) contain many more micro states and are therefore much more likely, energy tends to get transferred from ...
- particle physics - What is meant by low-energy approximation? - Physics ...It depends on the context: e.g., effective mass approximation used in semiconductor theory is a low-energy approximation: we assume that electrons and holes are not excited too far away from the band extremum, so that we can expand the dispersion relation near these point and neglect the transitions deep into the band or to other bands.
- Examples of a lower energy state being a lower entropy state?Of the particle reactions I know of, the lower-energy state is a great stand-in for the higher-entropy state. Big particles decay into jets of little particles, excited atoms emit photons unless forbidden, and so on. Since energy is conserved, I guess they're implicitly talking about low energy density when they say low-energy.
